Devices for supplementing conventional liquid fuels in internal combustion engines with gaseous fuel supplements

Abstract

Disclosed are several devices for supplementing conventional fuels (liquid or gas) in internal combustion engines with gaseous fuel supplements. The first device contains means for introducing a stream of hydrogen and/or oxygen gas into the spark gap. The second device contains means for introducing a gaseous fuel supplement into the combustion chamber through the piston. The third and fourth devices both contain means for introducing a gaseous fuel supplement into the venturi.

I claim: 
     
       1. In a spark plug having a spark gap between two electrodes, the improvement comprising: (a) first means for introducing a mixture of gases into said spark gap, said first means comprising a plurality of conduits which extend through one of said electrodes, and   (b) second means for connecting said spark plug to a spark plug wire which likewise contains a plurality of conduits for the gases, said second means comprising: (i) external threads on one of said spark plugs and the spark plug wire,   (ii) a cup-shaped collar carried by the other of said spark plug and the spark plug wire, said cup-shaped collar having internal threads sized to mate with said external threads,   (iii) one of the interfacing surfaces of said spark plug and the spark plug wire being convex and the other being correspondingly concave, and   (iv) the surface of the conductor in said spark plug being flared to provide the maximum possible contact with the interfacing surface of the conductor in spark plug wire.     
     
     
       2. In a spark plug as recited in claim 1, the further improvement wherein said gases are hydrogen and oxygen.
